           THE KEITH COMPANIES REPORTS FIRST QUARTER 2002 RESULTS WITH
          NET REVENUE REACHING RECORD LEVELS AT MORE THAN $21 MILLION

COSTA MESA, CA (May 2, 2002) ... The Keith Companies, Inc. (Nasdaq: TKCI), an
engineering and consulting services firm, today announced that net revenue for
the first quarter ended March 31, 2002 reached record levels, increasing to
$21.4 million, up 29 percent from last year's first quarter net revenue of $16.6
million.

     Net income for the first quarter of this year increased 5 percent to $1.44
million, or earnings per diluted share of $0.19 (based upon 7.8 million diluted
weighted average shares outstanding), as compared to net income of $1.37
million, or earnings per diluted share of $0.24 (based upon 5.8 million diluted
weighted average shares outstanding) for last year's first quarter. The 33
percent increase in diluted weighted average shares outstanding is predominately
due to the Company's Secondary Offering in May 2001.

     Chairman and CEO Aram Keith commented, "The record first quarter revenue
results are the direct result of successfully implementing our acquisition
strategy of expanding our resources and geographic reach, while striving to
achieve a better mix of business from each of the main industries we serve. Our
overall results were positive, but mixed performance within some of our
operating groups led to a slight decrease in organic net revenue for first
quarter 2002 vs. first quarter 2001. We continue to monitor our SG&A costs and
have made prudent cuts recently to





help improve operating margins and better position the Company for the current
economic environment. It is important to note that we have continued to maintain
our operating profit margin at levels well above other companies in the
Engineering Services Standard Industrial Classification (SIC) code.

     "During the first quarter," Keith added, "we experienced strong cash flow
by generating $4.4 million from operations and we acquired Michigan based ALNM
Group Inc. With forecasted annual net revenue approaching $100 million for 2002
and a strong balance sheet, we are well positioned to take the Company to its
next level of growth."

     The acquisition of ALNM gives The Keith Companies a solid presence in the
upper Midwest region, strengthens its resources in the public works and
infrastructure industries and provides the Company with a springboard from which
to continue to pursue its plan of growth and diversification into the Midwest.

     "It is difficult to predict with certainty the number and timing of any
future acquisitions," Keith said, "but we feel that our strong balance sheet and
in-place resources for due diligence and integration position us to continue our
strategy of acquiring companies that fit our target company profile."

     The Company's March 31, 2002 balance sheet remains strong with cash and
securities of $20.4 million, a current ratio of 3.1:1, a debt to equity ratio of
0.03:1 and shareholders' equity of $55.2 million.

     Gross profit in the 2002 first quarter increased to $7.0 million, up from
$5.7 million in last year's first quarter due to acquisitions. The Company's
SG&A expense increased to $4.7 million in the first quarter of this year, from
$3.3 million in last year's first quarter, due primarily to the added SG&A
expense from its acquired companies and costs associated with expanding the
Company's business.

NET REVENUE CONTRIBUTIONS FROM ACQUISITIONS

     Acquired companies contributed $5.2 million in net revenue for the first
quarter of 2002 as compared to the first quarter of 2001. This $5.2 million
includes one month of revenue contributed by Hook & Associates Engineering, Inc.
(acquired January 2001), one month of revenue contributed by ALNM Group, Inc.
(acquired March 2002), and a three-month revenue contribution from both Pacific
Engineering Corporation (acquired September 2001) and Universal Energy, Inc.
(acquired November 2001).

FINANCIAL GUIDANCE

     The Keith Companies' financial guidance for 2002 remains unchanged from the
guidance previously provided. The Company estimates net revenue for 2002 to
range from $92.0 million to $99.5 million with estimated diluted earnings per
share ranging from $0.87 to $1.00 ($0.21 to $0.25 for the second quarter, $0.25
to $0.29 for the third quarter and $0.22 to $0.26 for the fourth quarter) based
upon an estimated 8.0 million weighted average number of diluted shares
outstanding for the year.
